Factual error: In the bathroom scene at the motel where Lucy is in the shower and Mimi is using the toilet, Mimi flushes the toilet and Lucy yells "Ahh, freakin' cold," however, if someone flushes a toilet whilst another person is in the shower then this would result in the cold water being removed from the shower, so Lucy really should have yelled "freakin' hot," unless the toilet water was hot water.

Toward the beginning of their drive, while the girls are singing "Bye, Bye, Bye" the position of the window behind Mimi keeps changing. Sometimes it is all the way up, then it is part-way down, then back up again.
